FeaturesCast-on to an effortless new method of knitting socks, cuffs, hats, and many of other projects which are worked in the round, with the addi® FlexiFlips. Made specifically for North America, these specially designed 21cm circulars (3.5" tips with 1" cord) rest comfortably in the hand, and act as flexible double pointed needles. Easy to use, stitches are simply distributed over two needles, and then knit with the third - resulting in only two needle changes per row.
